Hitachi Japan have announced in its recent press release that they have a
new secret formula that prolong battery life twice as much in a lithium
ion battery, lasting up to 10 years without being replaced.
According to the press release, they replaced elements in traditional batteries to combat acid corrosion in the cathode material, stablising the structure, delaying degradation.
New Energy and Industrial Technology Development Organization (NEDO) established by the Japanese government have commissioned the research.
Let us hope these new batteries will be affordable and readily available in the near future.
